Study Highlights the Beginnings of a Beautiful Bacterial Friendship
October 24, 2018
Department of Biological Sciences' Chris Marx and colleagues representing three other universities published a study this week in the Proceedings of the National Academy of Sciences. The laboratory study addressed how two species can evolve a relationship that increases the chance of survival for both despite the energy costs to both. The experiment, which involved the bacteria Salmonella enterica and Escherichia coli, is the first to document the step-by-step emergence of a costly – in terms of energy – but mutually beneficial relationship between species.
